L-Serine is an amino acid which supports neuron growth / health. It also supports the production of purines, pyrimdines, and important amino acids such as Tryptophan, L-Cystine, and Glycine. L-Serine also supports the growth and maintenance of new cells.

While the body does produce some L-Serine, it does not do so in high enough quantities to meet all the body’s demand for it so an external supply from diet or supplementation is recommended.

Recommended Dosage

For general use as a supplement, our recommended L-Serine dosage is 2000 mg per day. (4x 500 mg capsules.) L-Serine is water soluble and so does not need to be taken with food. It is often used in the evening, as it has a beneficial effect on sleep quality.

While we typically don’t recommend a dosage of over 6,000 mg per day there have been studies showing its safe use at dosages as high as 15,000 mg per day. We recommend avoiding doses this high as there is a much higher potential for side effects.

L-Serine Side Effects

L-Serine is well tolerated with few side effects, but some have been reported especially at high doses. The most common side effects associated with L-Serine are diarrhea and GI discomfort. Please consult your physician before taking L-Serine.
